Remark
. Emulsion type silicones only have two components: Base Polymer+Catalsyt, no need of Cross-linker.
. Emulsion type silicones should be agitated thoroughly before use.
. Emulsion type silicones may freeze at low temperatures, so users in colder regions should take special care with regard to storage.
. Emulsion type silicones should be storage in a closed container at +10°C to +30°C temperature.
